Abstract

The invention belongs to the technical field of pharmaceutical preparations, and particularly relates to a pramipexole dihydrochloride oral film-dissolving agent pharmaceutical composition and a preparation method thereof. The composition provided by the invention comprises a polymer film-forming material, a plasticizer and the like. The film agent does not need to be taken with water, is convenient to take, good in taste and rapid to dissolve out, is very suitable for Parkinson's disease patients, especially patients suffering from chewing, dysphagia and hand tremor, greatly improves the compliance of the patients, and has good economic benefits and social benefits.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, in particular to a pramipexole hydrochloride orally dissolving film pharmaceutical composition and a preparation method thereof. Background technique [0002] Pramipexole hydrochloride (Pramipexole) is a new generation of non-ergot dopamine receptor agonist developed by Boehringer Ingelheim, Germany. It can highly selectively act on dopaminergic D2 and D3 receptors, stimulate the release of dopamine in the brain, and improve motor symptoms. It is the first-line drug for the treatment of Parkinson's disease. [0003] The chemical name of pramipexole is S-2-amino-4,5,6,7-tetrahydro-6-(propylamino)-benzothiazole, molecular formula C 10 h 17 N 3 S, relative molecular weight 211.33. Pramipexole hydrochloride is white or off-white crystalline powder, easily soluble in water, soluble in methanol, insoluble or slightly soluble in ethanol, almost insoluble in dichloromethane, very stable in ...
